I made some at the end of last year for summer consumption and so it sat for about 6 months. It had a very ‘cherry medicine’ flavor. I just opened a bottle last week and now… wow. That medicine flavor is gone and it’s very smooth.
Were I to do it again, which is quite possible, I would bulk age for a smidge longer. I didn’t have the same issue with skeeter pee though. So, maybe it was the berries? The only reason I might keep it in bulk to age vs bottle aging is if I wanted to adjust all of it somehow. (Ex backsweeten, remove acid, etc…)
You can always taste at intervals to see if it’s where you like it prior to bottling. I was able to drink the skeeter pee right away but it did seem to improve with time. Same for a mojito blend I did.
